I tried to allocate a marker to each plot in for loop but I could'nt. would you please help me with that?

I was able to give each plot a disired color but for marker the error shows up.

Many thanks

Try this:

markerShapes = {'.', 's', 'd', '^'}; % However many you need
for k = 1 : numPlots % numPlots must be less than the number of marker shapes.
    thisColor = rand(3, 1); % Random color or whatever...
    plot(x, y, markerShapes{k}, 'Color', thisColor);
    hold on;
end
